Frequently Asked Questions - JTMT01 Joy-It

How do I turn on the Joy-It JTMT01 multimeter?

To turn on the multimeter, turn the function selector to the desired measurement. The device will turn on automatically.

What should I do if the multimeter does not turn on?

Check if the batteries are installed correctly and are not discharged. Replace the batteries if necessary.

How do I change the batteries of the Joy-It JTMT01?

Remove the battery compartment cover on the back of the device. Replace the batteries with new ones, respecting the polarity.

How do I measure voltage with the multimeter?

Select the 'V' mode for DC or AC voltage, then connect the probes to the corresponding terminals and place them on the circuit to be measured.

Why does the multimeter show an incorrect reading?

Make sure you are using the correct measurement mode and that the probes are properly connected. Also check the battery condition.

How do I measure resistance with the Joy-It JTMT01?

Select the '9' mode to measure resistance, then connect the probes to the terminals of the resistor to be tested.

The multimeter shows 'OL' during my measurements, what does this mean?

'OL' means the measured value is outside the selected measurement range. Check the range and select an appropriate range.

How do I measure current with the multimeter?

Select the 'A' mode for current, then connect the probes in series with the circuit you want to measure.

How do I reset the multimeter?

To reset the multimeter, remove the batteries for a few minutes, then reinstall them.

Where can I find the user manual for the Joy-It JTMT01?

The user manual is available on the Joy-It website or may be provided with the product upon purchase.

TABLE DES MATIÈRES

Dear customer, thank you for choosing our product. In the following, we will show you what you need to bear in mind during commissioning and use.

Should you encounter any unexpected problems during use, please do not hesitate to contact us.

2. DEVICE OVERVIEW

BUTTON OPERATION FUNCTION
VΩ-14	Change measurement modes between voltage, resistance, diodes/continuity and capacitance
REL HOLD	Press briefly Pause current measurement Press long Switch to relative value measurement mode
AUTO MENU	Press briefly Start auto mode Press long Open menu
NVC LIVE Hz	Change measurement modes between frequency, temperature, NCV and live measurement
mA A	Switch between low current & high current measurement
	Press briefly Turn off the device Press long Turn on the device

3. MEASURING MODES

3.1 NORMAL MODE

In normal mode, automatic measurement and the measurement of voltage, resistance, diodes, continuity, capacitors, high current, low current, frequency, temperatures, NCV and current-carrying cables are not supported.

AUTOMATIC MEASUREMENT

Automatic measurement is performed automatically as soon as normal mode is started via the menu. Automatic measurement can also be started manually using the AUTO button.

The automatic measurement only supports the measurement of voltages and resistances, as well as continuity testing.

MANUAL MEASUREMENT

Switch to the desired measuring mode by pressing the corresponding button until the desired mode appears on the display.

NCV MEASUREMENT

Switch to NCV mode and slowly point the device with the NCV marker at the area to be measured. As soon as the sensor detects an electromagnetic field, an alarm is issued automatically.

The stronger the electromagnetic field, the faster the alarm is emitted. A corresponding message is also shown on the display:

No magnetic field Low magnetic field

Medium magnetic field Strong magnetic field

MEASUREMENT OF LIVE CABLES

Switch to live mode and connect only one measuring tip to the voltage channel.

Now touch the cable to be tested with the measuring tip. If a live cable is detected, an alarm is automatically emitted. A corresponding message is also shown on the display:

No live wire detected

Live wire detected

3.2 RECORDING MODE

The recording mode supports the measurement of voltages, resistances, diodes, continuity measurements, high current, low current, frequencies and temperatures.

In recording mode, a measurement graph and the extreme values of the current measurement are also displayed. Furthermore, up to 8 measured values can be stored temporarily by pressing the auto/menu button.

Please note that the measurement graph is deactivated for continuity measurements.

3.3 MONITORING MODE

The monitoring mode supports the measurement of voltages, currents and temperatures. In this mode, an alarm is issued automatically as soon as the preset limit values are exceeded or not reached.

To modify the limit value settings, open the settings menu and navigate to the Threshold settings menu item. Here you can set the corresponding minimum and maximum values.

Below minimum value Parameters in the normal range
Maximum value exceeded
